ANTHONY B. ZIERLEYN, OF GRAND RAPIDS, MICHIGAN ELECTRIC TIME-SWITCH.

T all whom it may concern.-

Be it known that I, Au'rnorn' B. ZiERLEYN, a citizen of the UnitedStates, residing at Grand Rn. )ids, in the county of Kent and State ofIt chi an, have invented a new and useful Electric limo-Swi tch, ofwhich the following is o specification.

This invention relates to electric timoswitches, and has for itsprincipal object to provide a means for automaticolly'connectmg-saddisconnect-in an electric circuit so that the circuit may s closed orbroken for any desired length of time,

A further ob ect of the invention is to provide a. timing device of thischaracter in which the time of closing the circuit and the time ofopeningthocircuit may be I indepondcntl of each other. i

provide an electric time-switch of simplo and inexpensive constructionand which may be connected at comonrativelysmall cost to an ordinaryclock-tram.

With thesoand other objects in view, as

Bearing against the 24 arethaupper bifurcated ends of lovers and 3 1, pivoted in suitablebrackctsBZ, and the lower ends of which serve to control the movement ofthe circuitclosing device. The upper ends of these arms refereed into'ment with the hubs 24 by means of springs 3, and as soon as one of fthe shonlders of one of the timing-cams come 0 osito one of the In 26the timing-com 81 :5 hub'wiil more out sard under the influonce at s 33,and the cimuit-controiling lover w be swung on its, pivot for the urposeof releasing one of the circuit-contt-o ing members. At a central pointunder the' clock-trek: is arranged a motcllic'standsrd 36 carrying apair of slightly-spaced metallic plates 37, arranged for the receptionof the opposite ends of a. pair of switch-blades 39 and 40, and whenboth blades are engaged withthc plate 37 the lighting or other circuitis closed, and when either is disconnected the circuit is open.

The switch-blade 39 is carried by. a block 41 formed of porcelain orother material, and tho rear end of the blade is connected mechsnicollyand electrically to a. stem 42,that

lis arranged to slide withhi sv recess formed be- 13, which intermesheswith two gears 14 and ofeach other mjchthe some manner as an v ordinaryelarmoficlianism 13 set, V V A still fun or object of the invontionis'toreduced portion of thestem is surrounded by a helical compressiomspring50, hearing at one end ainst the collar 47 and at the oposite em?against a lug 51, carried by the ower plate 44 and provided with anopening for the passage of the reduced portion of the stem. This springtends normally to move the stem outward from the position shown in Fig.l, and thus pull the switch-blade 39 from engagement with the plates 37.

The switchfblade 39 is held from 'rotative movement by a pair offlan cs53, (see Fig. 2,) formed integral with the ase l() and en- "aging theends of the blades which project be end the bloek'41; The block 41 isprovided with a vertically-dis osed opening 54, in which is arranged ahe ical compressionspring 55, held in place by upper and lower plates56, secured to the block. -These plates are provided with openings forthe passage of a verticaly-movable rod 58, car rying at its upper en acatch 59 beveled on one face ,and provided with an abrupt verticalshoulder designed to en age with the clock-controlled lever 31, an whenso engaged the lever will hold the switclrblade 39 in engagement withthe plates 37 but when lever 31 is moved at the end of a predeterminedperiod qf time to one side of the catch 59 the spring 50 will withdrawthe blade 39 from engagement with the plates 37 for the purpose ofbreaking the circuit. The blade 40 is alsg' mounted in a block 41, whichcarries a spring-pressed catch 59, of a construction similar to thecatch 59, and the stem 42', attached to the blade 40, is acted upon by aspring 50', which tendsto move the blade 40 into enga ement 'with thecatch 59. The upper cm of the stem is provided with a knob 48 to permitmanual adjustment of the position of the blade 40. The catch 5!) iscngaged by the lever 30 and held by said levar with the blade 40 in theposition shown in Fig. l--tl|at is to say, out of contact with theplates 37. The stem 42' is guided between two plates 43 and 44; thelower plate 44 carrying a binding-screw 45 for connection to acircuit-wire 2:.

The normal position of the parts is shown in Figs. 1 and 3, with theblade 40 out of engagement with the plates 37 and the blade 39 engagingsaid plates 37, the circuit being broken. The pointers 20, carricd bythe arbors 16 and 17, are then ad'nstcd to time the closing of thecircuit ad the subsequent opening of the circuit, and at the proper timelever 30 will be released and forced to move by its spring fromengagement with the catch 59', whereupon the spring 50 will act to forcethe blade 40 into engagement with the plates 37, thus completing acircuit from line so through binding-screw 45', plates 44 43, stem 42',blade 40, plates 37, blade 39, stem 42, plates 43 44, binding-screw 45,and circult-wire .c. The circuitwill then be closed until the gear 15 inrotating carries its cam to a position to release the lever 31,whereupon said lever is forced by its spr'n :g from enga gement withtlie catch 59 and spring 50 imme diately withdraws the blade 39 fromengagement with the plates 37, breaking the circuit.

It will be seen that the time of closing the circuit and the time ofopening the circuit may be independentl adjusted and the curcent may beopt on or an desired length of time, this being of especial value inmany cases where it is desired to avoid waste of currentas, forinstance, in the lighting of a show-window darn: g a portion of theevening or the lighting of a store alter the closing hour, so that alight may be kept burning throughout the night and extinguished early inthe morning.
